SPECIFICATION forming part of Letters Patent No. 392.14%, dated October 30, 1888.

Application filed December 6, 1887. v Serial No. 257,091. (No model.)

To aZZ whom it mag/concern,.-

Be it known that I, HERMANN BORMANN, a subject of the Emperor of Germany, but now resldlng at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvama, have invented certain new and useful 'Improvements in Machines for Making Sewing Thread or Cord, of which the following 1s a specification. j

My lnvention has for its object to provide a machine of comparatively simple construction for making sewing thread or cord composed of two or more strands of ilax or other vegetable or animal material and one or more metallic wire or wires intertwisted together and laying or twisting two or more of said strands in the opposite or same direction to that in which thewire or wires is or are intertwistcd with the fibrous vegetable or animal material to form a .two or more ply perfectly-pliable sewing thread or cord for various purposes.

Previous to my invention the twisting with brous material of a wire or wires has been conducted on an ordinary ropewalk,whieh to a greater or less extent wasobjectionable, because of the slowness of its production and the Want of uniformity in the twist thereof; but one ofthe chief difficulties encountered has been the breaking short or flying 0E of the Wire inthe twisting operation; but these objectiona- `ble features I have overcome and have designed a machine in 4which for the first time, as far as Iam aware,it is rendered possible to intert'wist a wire or wires of one nature with fibrous vegetable or animal material of an entirely different nature, and thereby producing a perfectly-pliable thread or cord for sewing boots or shoes and capable of being used for shoe strings, fishing-lines, and many other purposes.

|The nature and characteristic features of my improved machine for the productiouof the thread or cord will be fully understood by reference to the accompanying drawings, forming part hereof, and in which-- Figure 1 is a front elevation of my improved twisting apparatus, parts being broken away. Fig. 2 1s a vertical cross-scction thereof. Fig.

5o 3 is a top view, and Fig. 4 is a horizontal section on the line :v of Fig. 2.

It is customary in such type of machinery to provide several sets of twisting mechanisms in a single frame, and as each is a duplicate of the others in construction and operation I have therefore in Fig. l only shown three sets of such mechanisms; but it will nevertheless be understood that any desired number may be provided for increasing the production of the improved cord or thread of whatever given ply may be desircdv-as, for example, one, two, three, or more ply.

Referring to the accompanying drawings forv a further description of the invention, A represents the standards or supporting-frames, of stout material, set at suitable distances apart, and connected with each other by means of upper and lower longitudinal bars or rails, A and A2. rI he lower portion of each standard A projects outward, forming a su pport, a, for

the reception of the table A, with its projecting flange a. Each support a is provided with a recess for the reception of the longitudinal bar A4, and a similar longitudinal bar, A5, is secured to and supported on the lower transverse frame,l a, of the standard A. The

longitudinal bar A is provided at suitable distances apart with apertures a3, forming journal-bearings for the spindles B, and the longitudinal bar A5 is provided with sockets a4 for receiving the lower extremities of the spindles B. A hub, b, is rigidly secured to each spindle B, for holding in position a V-shaped groove-pulley, B', loosely mounted on each spindle.

Formed integral with or secured to the pulley B is a hub or collar, b', with a notched upper surface for engaging a clutch, b2, feathered tothe spindle B and operated by a bifurcated horizontal arm, b3. The upper extremity of each spindle has secured to it a circular creel or llier, D, carrying as many spool' holders or spindles d or cups d as there are strands of fibrous material and wire or wires to be intertwistcd together, and in each creel or llier D, at suitable distances apart and concentric therewith, are guide and tension spindles or posts d2, provided with eyes d"l in their upper extremities.

With the upper transverse bar or frame, ai, of cach standard A are formed brackets a6 for supporting the longitudinal beams A and A7,

ICO

and in these beams, atsnitable distances apart, are formed bearings for receiving each horizontal shaft c, on which is rigidly secured a hub or collar, e', for holding inA position a grooved pulley, ll, loosely mounted on said shaft.

Formed integral with or secured to the pnlley E is a collar or hub, c, having a notched outer surface for engaging a clutch, e, feathered to the horizontal shaft c. This clutch c is operated by the bifurcated arm c ofa bellcrank lever, e, pivoted at its inner extremity to a bracket, c, secured to the longitudinal beam or bar AT. The forward extremity of the bellcranlt lever cJ is pivoted to a vertical rod, el, suitably attached to one extremity of the bifurcated horizontal arm if* of the clutch b, which is feathered to the spindle B. The vertical rod e7 passes through a guide or eye, es, secured to the inner edge of the table A3, which serves to guide aud insure regularity in thevertieal movement thereof. Centrally to this rod eT is pivoted a horizontal handlever,f, held in bearings provided therefor in the frame A, attached to the front of the machine, for engaging and disengaging the clutches bt and ci. Secured in the face of this frame A is a. guide, f, having an eye, and to a similar frame, A', attached to the front of the machine ashort distance above the former frame, is a guide,f'', having an eye. Both of these guides serve to direct the cord or thread from the creol or flier to the spool in a vertical course, to be presently fully described.

The outer portion of each shaft c is prefer ably formed square to accommodate the spool h and hold thesame rigidly in position thereon. ln the drawings areshown only a single series of fliers and mechanism for twisting the cord or thread and automatically laying up the cord or thread onto spools; but it is obvious that with but slight modification of the frame-work the mechanism for operating the machine might be arranged so that two rows of spindies, fliers, and spools could be operated from the same driving-shaft and each ilier or ereel run independently oi' the others, as hereinafter l'ully explained.

The main shaft C of the machine is held in journal-boxes c, mounted on the transverse bars a2 of the standards A. This shaft receives its motion from any suitable source by means ofthe belt c' and pulley c", as shown in Fig. 2. On the main driving shaft C are rigidly mounted as many grooved pulleys C as there are spindles to be driven. Motion is imparted to the creel or licr l) by means of the belt d, passing around the grooved pulley C of the shaft C and the smaller pulley, B', of the spindie D.

A spool, h, is mounted on the shaft c, and motion is imparted thereto by means of a belt, c, passing around a grooved pulley, E, and around a similar but smaller grooved pulley, c", mounted on the couuter-shaft F, held in journal-boxesf", supported on the transverse bars a7 of each standard A. This shaft F has rotary motion communicated to it from the main driving-shaft C by means of a pinion, d, which meshes with a gear-wheel, C, mounted on an intermediate shaft, c, held in journalboxes e, which are supported on the transverse bars a of the standards A. To the intermed iate shaft, c, is secured a eone-sbaped pulley` f. Motion is imparted to the countershaft F, provided with a similar cone-shaped pulley, f, by means of a belt, f, passing around said cone-shaped pulleys f* and fi. These cone-shaped pulleys are employed to insure an even or uniform twist throughout of the cord or thread laid up or wound automatically upon the spool or bobbin h-that is to say, as the speed of the llier or creci D is at all times a uniform one, and as the core of the spool h is constantly increasing in diameter, it therefore becomes necessary to be able to decrease the speed of each spool, because unless decreased the cord or thread being laid up onto the spools from the respective fliers or creeis D would be apt to have more twist in one portion than in another; but this is entirely overcome by the use and arrangement of the cone-shaped pulleys operating in the manner to be described.

The beltf6 is shifted on the cone-shaped pnllcys f" and f5 by means of guides f7 and f", mounted on wornmiutsf. These worm-nuts are actuated by worms fm and f, journaled in bearings provided to receive them in the transverse bars a of the standard A. These worms f" and f have motion imparted to them from the shafty by means of the beltfi,

ywhich passes around' the pulley f 6, mounted ou the shaft f/l, and also around the pulleyf", rigidly secured to the wormf. To revolve both worms simultaneously, two pulleys, f l and f, similar in diameter, are rigidly secured to the worms f andf", around which pulleys a belt, f", passes, as clearly illustrated in Figs. 1 and 2.

To automatically lay up the cord or thread onto the spool h, mounted ou the shaft c, a lon gitudinal U-shaped rod, i, is provided, extending the entire length of the machine, having as many eyes or guides i secured thereto as there are fliers or creeis D. This rod z' at each end is formed integral with a horizontal sliding rod, moving freely in bearings 1"',suitably secured to the upper transverse frames, ai, of the standards A, as shown in Fig. 3. These rods i and i2 are moved back and forth by connecting-rods t, pivoted to hubs or collars if', mounted on the horizontal sliding rods i2, and to a crank-disk, i", which is rigidly secured to the shaft il. Motion is ilnparted to this shaft from the counter-shaft F through the rtf intervention of the pinion r/,iwhich is mounted on said counter-shaft F. This pinion meshes with the gear-wheel G, mounted on an intermediate shaft, g', carrying a worm, y", which engages with a worm-wheel, G', secured to a vertical shaft, g3. The shaft g3 has on its upper extremity a beveled pinion, g, which meshes with a beveled wheel, 11", mounted on chine may be explained in the following-man ner: The fibrous vegetable or animal material, if in balls, is placed in the cups d', or, if wound upon bobbins, mounted on spindles or holders d, and the spools of wire likewise placed on o ne or more of the holders d, mounted on the circular creel or flier D, as shown in Figs. 1

' Y and2. The several strands are led upward through the eyes d in order to insure a proper tension and a regulated delivery of the strands of brous vegetable or animal material, and metallic wires to be intertwisted together through the eyes or guides f, f2, and t" and the ends fastened to the spool h in any suitable manuer. Motion is now communicated to the main driving-shaft C, which causes each flier or creel to be actuated for twisting or intertwisting the several strands of brous material and wire or wires uniformly into a cord,while the spooling mechanism, before described, is automatically laying up the cord or thread evenly onto each bobbin or spool h.

If from any cause one of the strands of fibrous material or the wire or wires should break down while the machine is in full operation, the flier D and also the bobbin or spool lt may be readily and quickly stopped by simply depressing tlie lever f, which will cause the `vcrtical rod eto be raised and the bell-crank lever c5 and horizontal arm b actuated thereby to release the pulleys B and E from their respective clutches Ifl and e, feathered to and sliding on the shaft e and spindle B, and leaving the same at astandstill,while the pulleys continue to revolve. After the damage has been repaired the flier D and spool h may again beA started up by simply elevating the hand-lever f, thereby causing the clutches b and e3 to again engage the pulleys B and E on the spindle B and shaft aand the operation-resumed until the spools are filled in the manner hereinbefore fully described for producing what is termed a single-ply threador cord.

To produce a thread or cord of more than a single ply-for example, a three-ply thread or cord-three of the spools h, filled with the cord or thread having the wire or wires combined therewith, may be removed from the shaft e and mounted on the holders d of the llier or ereel D, and the three-wired strands passed around the eyes d*1 of the guides d in the creel or dier D the requisite number of times to attain a proper tension, and these strands passed thence upward through the guidesf, f, and i to the spool h, firmly held on the shaft e. The machine is then started up, laying up the three-wired'tibrous strands in the same direction in which the siuglestrands having the wire intertwisted therewith are formed; but I have found thatlthe best results are obtained by twisting the three-ply cord in the opposite direction to that in which the single strands are laid up, which can be readily accomplished by simply changing the position of the belt d, passing around the grooved pulleys C and B', as shown, for instance, in Figs. 1 and 2, to the posit-ion illustrated in Fig. 1 to the right, in which three spools of cord or thread are shown mounted ou a cre'el or iiier, D. By this change of the belt d* a reversal in the movement of the twisting mechanism of 8o the machine will be insured for the accomplishment of the-purpose desired in a most satisfactory manner.

Having thus described the nature and ob jects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
